gives a graphics context whose product ultimately appears on screen. But the
full content of the view must be redrawn each time drawRect: runs, in contrast
to pre-10.14 where drawings were added to the previous window content.
- That is why FLView maintains a bitmap (view->aux_bitmap) equal to the last content of the FLView.
- At the beginning of drawRect:, aux_bitmap is copied to the graphics context,
- then drawRect: does its drawing, finally the view's graphical content as it is at the end of

+ That is why FLView maintains a bitmap (view->aux_bitmap) to which FLTK directs all drawings.
+ At the end of drawRect:, the content of that bitmap is copied to the graphics context.
+
A problem arises to support drawing done outside Fl_X::flush(), that is,
after the app calls Fl_Window::make_current() at any time it wants.
That situation is identified by the condition (views_use_CA && !through_drawRect).
A graphics context usable outside drawRect: that ultimately appears on screen,
if it exists, was not identified. Drawing operations after the call to Fl_Window::make_current()
- are directed to aux_bitmap. Fl_Window::make_current() sets to YES the direct_draw member
- of the FLView and also calls [view setNeedsDisplay:YES] which instructs the system to
- run drawRect: at the next event loop. Later, when drawRect: runs, the content of
- aux_bitmap is copied to drawRect's graphics context and direct_draw is set to NO.
